Grand gusset failure

The 850 ft arched truss bridge over Grand River in Cleveland underwent a midair repair scheme because the bridge's thick gusset plates were damaged. The repair was conducted by attaching jacking brackets to the lower chords of the failed joint and to strain gauge members. The strain gauge members were realigned through post-tensioning so that partial replacement gussets could be positioned. Although the repair of the damaged part of the bridge was complicated, it was completed in five-months time.
